Horn upgrade DIY

Got a chance to upgrade my horns from OEM to Fiamm Electric Horns. What a huge difference. The whiny tiny horns are gone, now I have the same normal horns which my Lexus has (Denso).

Had to remove the one by the alternator and the one by the radiator. I installed the pair right in the bottom air dam, there was a hole with a 10 mm bolt, in the same bracket as the existing mount, but this was lower. So I decided to mount it low and away from sight. I acutally mounted it where the original one was but it so so visible through the grille and since they were not painted, it looked tacky.

When I removed the OEM horns (and a lot of the other horns I have done, Acura and Toyota), I have always wondered why they were split. One is normally tucked away hidden, the other one in plain sight. The reason: The alarm. If the thief can get to your horn, then your audible alarm is already gone.

The only concern is that now the horns are very accessible for the thief to cut off. Specially that I am missing the left side plastic undercover! But who knows where the alarm's coming from? I will also try to paint it flat black so that it is discrete.

Pics to follow.

I can not tell you how happy I am to hear the horns. When you hit the alarm...

When there are no cars and houses around, I am horn happy.

Nothing like a good horn, eh?
I hate the wimpy stock horns. I'll eventually swap mine out too, but its not super high on my priority list.

It's on my list - and fairly high on the list - just not sure which horns to go with yet, still researching...

considering air horns, since no one seems to notice when I'm blowing the horn at them.

I should have painted the brackets so they are not as visible. Maybe I will one day.

Ever heard a Lexus ES350 or RX350 horn, that's identical.

Side by side sound clips would be very helpful in determining if I want to do this mod too

Rochester did his horn upgrade. Nice work he did. He put it in a better mount than I did.

Looking at these pictures, the 5.0 gen and the 5.5 gen have entirely different horn configurations. I'm glad you bumped this thread, it answers some questions floating around from the other one...

...and now we cross-reference, for posterity.

LOL, I was wondering while reading your post. Did not ring a bell. Now I know.

Mine's all the way down, I did not have space right in front of the radiator. And there was a hole conveniently located further down, I went for it.

It is true that you will need to twist, bend to get your mount the way you want it.

Is it really necessary to put the horn by the lower grille? You can't keep it where the stock one was on the 5th gen? I'm OCD along with pepox369 and I would hate to put it elsewhere. Thanks

For louder horns, you could just leave the stock two in front of the radiator, and then add these:

They definitely get people's attention when I want. Just make sure you use a relay (stock horn wire for signal, a fused wire from battery run under radiator support, ground to mounting bracket, and power to compressor tucked behind washer reservoir filler neck), or else you'll keep blowing your horn fuse after 2 seconds. It's also in the stock location for the alarm horn, so no one can tamper with it to turn off the extremely loud audible alarm.

(Disregard the stainless steel lines that don't connect to anything. They're for a more permanent PCV catch can install I never finished......)
